<VV> Serial numbers, differential questions and Tom Keosababi an's car

[Sadek Charles H DLVA]

Ken,
	The Tech guide, purchased thru CORSA or Clarks or Lon's Corvair
Underground will provide you will all of the numbers you need. Clark's or
Lon's catalog has a wealth of info.

AFAIK, GM did NOT offer a 4.11.  They offered a 3.89 in early cars? and
trucks (FCs).

Don Yenko offered 3.89s in some of his cars and it was used for some of the
race cars.  Usually the 3.55 was better. Doubt if he offered a 4.11-I don't
remember if the 4.11 was fabricated by the time he quit making Yenkos/kits.
If it was, I am positive he would have built one if you paid him to do it.

Early vs. late flywheels and pressure plates need to be used together.  Ring
gear is welded to the pressure plate.  You need a shop manual. 

Pistons?  Depends on how much you want to spend and application. 

Others may have answers for the rest of your questions.

Subject: <VV> Serial numbers, differential questions and Tom Keosababian's
car

1) Where do I find serial number charts for head codes, crankshaft codes and
crankcase codes too?  Specifically what does crankcase code "TO201Y" tell
me?  T= Tonowanda and Y= Turbocharged IIRC.  Its been a looooooooong time
since I've dealt W/Corvair codes!
 
I've ordered "Corvair - A Junkyard Primer" are they in that book?
 
2) What year did Chevy offer 4.11:1 Corvair differential ratios?  I know
that the Yenko Stingers ran them but I always thought that they were made up
by Don from the Chevy parts bin and "sorta"homolegated" just for racing.  Is
that indeed correct?   Did they ever come stock on Vans or FC vehicles?   
 
3) How do you tell what year and model flywheel/ring gear sets came out of ?
What are the best ones for road racing?  For drag racing?  For running at
Bonneville?
 
4) Where can I get reprints of the Tom Keosababian articles on his 173+ MPH
car?
 
5) What is the largest engine you can build using the VW cylinders?  Where
are they they cheapest (new)?  Can you find them used?  What is the hot
set-up for pistons?
 
ITYIA for any and all help with these questions.
